[Set] RED DOT SIGHT NAUTILUS 1X30 QD [Vector Optics]. + Battery R03 AAA 1,5V HEAVY DUTY [Rocketl]

Great red dot, the 30mm lens is very helpful for easier target acquiring, the dot it self is pretty bright and has 11 levels of adjustment, also the power button switches between a high and low brightness modes.
I love the quick release handle as it's very fast to attach and take down after a match.
Runs on a single AAA battery which lasts quite a bit.
Easy and quick windage and range knobs
The only reason i gave it 4 stars is the fact that there are no scope protectors available for it on the market or a place to mount them with the covers attached to it, I had to 3D print a honeycomb 30mm wide which fits inside the scope for extra protection, it even allows the cover to be closed with it inside.

It i a top notch product, the glass is super clear, the dot is good but the photo senzor how should auto ilummination work, it from 100%metal it'worth the money depending on how much do you want to spend,it beats all holoo's if u play in the night the only negative point is where do you buy a honey comb1x30 for this product
